1.Remove the four bolts (ref# 9) and

pull intake endcap (ref# 11), from the pump. The endcap should separate from the material head (ref# 21), with the ball guide (ref# 17) attached. If the ball guide remains in the material head, pry out with a screw driver.

2.Clamp endcap in vise with the ball guide facing up.

3.Pry off the ball guide and remove intake ball (ref# 14) and spring (ref# 15).

4.Remove seat from endcap. NOTE; The seat is not secured with any Loc-Tite, however dried paint may cause difficulty in removing seat.

5.Remove the crush washer (ref# 12).

6.Thoroughly clean and inspect all parts. Replace any worn or damaged parts.

7.Place clean endcap in vise with o-ring (ref# 19) groove facing up.

8.Assembly of parts is the reverse of removal; washer (ref# 12), seat (ref# 13), and ball (ref# 14). NOTE; A new compression washer should be used each time the endcap is removed

9.If the ball guide (ref# 17) and ball stop (ref# 18) were separated during removal, re-assemble the two. NOTE; The step on the ball stop must face outwards ( Towards hydrapulse membrane ).

10.Place the spring (ref# 15) into the ball guide so the smaller end of the spring will contact the ball.

11.Assemble the ball guide, with spring, onto the endcap over the already installed ball and seat. Push down on the ball guide so that the ball guide o-ring (ref# 16) locks the assembly together.

12.Place o-ring (ref# 19) in the groove on the face of the endcap.

13.Install the entire endcap assembly onto the material head with the four bolts (ref# 9). Torque bolts, using a crisscross pattern, to 20 ft. lbs. Repeat torquing procedure using 30 ft. lbs.

NOTE: Effective March 1997, and beginning with serial number 140056, a new style Hydrapulse “Intake” assembly is used. The changes effect the Endcap (ref# 11), Crush Washer (ref # 12), Ball Guide (ref# 17), Ball Stop (ref# 18), and the Material Head (ref# 21). The most significant change is to the endcap. Gone is the o-ring, formerly located under the intake seat. The endcap is machined flush and a new crush washer is now placed in before the seat ( crush washer is placed under the seat ). The seat will be held in place through the compression of parts during assembly.
